A hazmat transportation monitoring system based on Global Positioning System / Beidou Navigation Satellite System and RS485 bus

摘要

With the demand for road transport of hazmat in the past few years, accidents occur frequently during the dangerous goods transportation and road transportation safety issues become increasingly prominent. Therefore, it is urgent to make full use of technical measures of information collection and transmission to monitor the state of dangerous goods. A real-time system is put forward in this paper, which can monitor the state of hazmat during the transportation by using Global Positioning System (GPS)/BeiDou Navigation Satellite System (BDS) technology and sensor acquisition modules, which is based on RS485 bus technology. Combine the above technical schemes with General Packet Radio Service (GPRS) radio transmission, Radio Frequency Identification (RFID) and Geographic Information System (GIS) technology, the system can monitor the position information and crucial state information of the dangerous goods during the transportation. The system can fundamentally solve the safety issues of hazmat transport, and it is helpful to achieve scientific management in further.
